In this project, students work in small groups to formally characterize an aspect of a local igneous rock, based on petrography, hand sample descriptions, and SEM and/or CL analyses. Students have two lab sessions and a field trip dedicated to working on this suite of rocks: one for detailed petrographic analyses and another SEM or CL imaging and analysis. The field trip is the field component of the project. The individual labs are ungraded, but all are required for completion of the project. Papers must include the following sections: Introduction, Geologic History, Petrography, Chemical Analysis, Discussion, References, Appendix (contains copies of ALL notes, calculations, drafts and revisions)
